TPS62230: DESIGN REVIEW

Shubham Yadav

Part Number: TPS62230

Tool/software:

Dear Sir,

We have used your TPS62237DRYT buck converter in your design to generate 3V from a 5V input source. Please review my design and let us know if any changes are required in it. FYI, the load at 3V3 is drawing 400 mA of current, as shown in the attached image. I have attached the image for your reference; please review it and let me know if any changes are required or all is proper.

Waiting for your reply,

Thanks & Regards,
Shubham Yadav

Hi Shubham,

You need to increase the input and output caps. Input should be at least 2.2uF and output 4.7uF.

Best regards,
